         Piyali Chatterjee    (PC)
         Matthias Rheinhardt  (MR)

The meeting was held at CERN in hybrid with PB, AB, and MR in person.

1. approval of the agenda

The agenda proposed by Philippe was approved.

2. secretary of the meeting

Philippe is the secretary and writes the minutes.

3. approval the minutes of the meetings of 12 May and 12 June 2025

After a short discussion, certain statements in the 12 May minutes were anonymized.
The minutes of both previous meetings were approved unanimously.

4. next Pencil Code User Meeting (2026)

The offers from Clara Dehman (University of Alicante) and Yasuhito Narita (TU Braunschweig) are still valid.
Also Jennifer expressed interest to organize one of the upcoming PCUM meetings in Bonn.
As opening another call for more proposals would not change the situation of Clara, who has a grant until December 2026, the PCSC voted unanimously to host the next meeting at University of Alicante.

5. other business

- code of conduct
Due to the unchanged situation of certain allegations and accusations being made against members of our community, the PCSC discussed what action should be taken, if any.
Matthias thinks that any action would not lead to a change of view at the accusing person.
Philippe thinks that the PCSC should take at least a minimal action and assess whether a breach of the code of conduct did happen and whether the PCSC does or does not agree with the statements made.

- using branches for development
Some individuals proposed that all development should happen on branches that get merged only after they passed all auto-tests. It was claimed that this would solve and prevent all issues we had in the past with broken auto-tests or changes done to the code and in particular to reference files of auto-tests.
Axel, Matthias, and Philippe strongly disagree with these claims and find that the incident we had in 2018, with Fred changing the hyperdiffusion code and Philippe fixing broken auto-tests in the same time, would anyway have occurred, no matter if everyone worked on branches or not. The reasons are that the affected auto-tests were already broken since long time before this incident occurred. Also the maintainer of the affected auto-test was not reacting to his test was failing on different machines and different compilers for long time.
Axel proposed that some written documentation be made available.
